To help celebrate General Hospital’s 50th anniversary on April 1, EW obtained an exclusive look at the very first scenes from the long-running ABC sudser – which, naturally, begins with images of busy nurses (and a fairly ominous soundtrack). Brace yourself for the Twilight Zone feel of the original black and white episode, and see if you recognize anyone!

Want more? You’re in luck: SOAPnet will air a 50-hour marathon of the series, starting with the ENTIRE first episode, beginning tonight at 10 ET/PT and continuing through April 1, when a special 50th anniversary episode of GH will air from 2-3 p.m. ET/1 p.m. PT/CT on ABC.
